<p>Hey guys regarding this one question you all are discussing, the one with what properties are affected by temperature, can anyone post the actual question and options?</p>
<p>I still do not get why the answer to the temperature Q(not a function of) can’t be total energy of gas.

<p>“According to postulate 4 of the kinetic theory, gas molecules have constant total kinetic energy.”</p>
<p>Energy is constant, and adding temperature only increases the average kinetic energy. Also look at the other link to see that density does change at different temperatures. You also should factor critical points and supercritical fluids into this.</p>

<p>The question was:
Which of the following is NOT a function of temperature
A. pressure
B. deviation from ideal gas behavior
C. total energy of the gas
D. density
E. volume/velocity</p>
<p>I got C as the answer, but people are saying it’s density.</p>
<p>Dear CB,</p>
<p>I am writing this post to inform you that you should omit the question regarding the temperature (not a function of). It would be greatly appreciated. </p>
<p>Thanks,

<p>Are you sure the question didn’t also say “under constant volume”? I remember something like that… </p>
<p>A - Pressure is a function, ideal gas law
B - High T low P is Ideal gas conditions, so this is a function of temp
C - Internal energy of a system is temperature dependent
D - Density is a function of temperature IF VOLUME IS NOT CONSTANT. If volume is constant, then density is not a function of temp.
E - Velocity is definitely a function of temperature…</p>
<p>I think it’s safe to assume that volume was constant in the question…i swear i remember that.</p>
<p>^Volume was constant, but doesn’t the constant total energy theory still apply?</p>
<p>I’m iffy about the internal energy - however, you can only pick up to one choice. I would place my bets on density.</p>
<p>Mass is constant regardless of the conditions, and that’s one of the most fundamental facts of nature. If volume is constant as well, then you automatically have constant density, and this means that it isn’t a function of temperature.</p>
<p>can someone explain the N oxidation? I put from 5+ to 4+ but Im hearing 5+ to 3-</p>
<p>I had no clue lol</p>
<p>for the one with a starting volume of 8L, was the ending volume 8L as well?</p>
<p>it was NO3^-1 to NH4^+ i think. +5 into -3.</p>
<p>wynter-I got 8 L for that question too</p>
<p>Okay good. i was really silly and didnt see both were halved in the beginning so i set up the p1v1/t1 = p2v2/t2 proportion and i kept getting that the new pressure was 8/3L…idk why maybe thats not even a formula hahah but then i realized that the numerator and denominator were both cut in half so v had to stay the same</p>
<p>@LilBallerx8 - I got +5 to -3.</p>
<p>@wynter - I got that too.</p>
<p>God I just realized I made so many silly mistakes. ><</p>
<p>why wasnt N2 covalent bonding?</p>
<p>Uh…does someone recall the values of the “8L” PV/T = PV/T problem? I seem to recall either getting 2L or 8L but can’t remember…</p>
<p>8L we think … look up
@Lance - I didnt really look to see if it was at standard conditions but i remember graphing density as a function of temperature in chem lab so i also went with C. I’m pretty sure that C is a right answer, but if it was at standard conditions, E also is.</p>
<p>No, I saw the concensus about 8L, but I was looking for original values from the actual question. Example: 1 ATM increased to 2 ATM, 200K cooled down to 100K. Stuff like that.</p>
<p>I believe it was 1.5L to 0.75L and 200K to 100K and original volume was 8L</p>
<p>oh my goodness I thought the C –> Co2 one was oxidation? Addition of O? :o</p>
